Μπαταρίες LiFePO4 are taking “charge” of the battery world. But what exactly does “LiFePO4” mean? What makes these batteries better than other types?
Read on for the answer to these questions and more.
Τι είναι οι μπαταρίες LiFePO4;
LiFePO4 batteries are a type of lithium battery built from lithium iron phosphate. Other batteries in the lithium category include:
Lithium Cobalt Oxide (LiCoO22)
Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2)
Lithium Titanate (LTO)
Lithium Manganese Oxide (LiMn2O4)
Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2)
You might remember some of these elements from chemistry class. That’s where you spent hours memorizing the periodic table (or, staring at it on the teacher’s wall). That’s where you performed experiments (or, stared at your crush while pretending to pay attention to the experiments).
Of course, every now and then a student adores experiments and ends up becoming a chemist. And it was chemists who discovered the best lithium combinations for batteries. Long story short, that’s how the LiFePO4 battery was born. (In 1996, by the University of Texas, to be exact). LiFePO4 is now known as the safest, most stable and most reliable lithium battery.
LiFePO4 vs. Lithium Ion Batteries
Now that we know what LiFePO4 batteries are, let’s discuss what makes LiFePO4 better than lithium ion and other lithium batteries.
The LiFePO4 battery isn’t great for wearable devices like watches. Because they have a lower energy density compared to other lithium-ion batteries. That said, for things like solar energy systems, RVs, golf carts, bass boats, and electric motorcycles, it’s the best by far. Why?
Well, for one, the cycle life of a LiFePO4 battery is over 4x that of other lithium ion batteries.
It’s also the safest lithium battery type on the market, safer than lithiom ion and other battery types.
And last but not least, LiFePO4 batteries can not only reach 3,000-5,000 cycles or more… They can reach 100% depth of discharge (DOD). Why does that matter? Because that means, with LiFePO4 (unlike other batteries) you don’t have to worry about over discharging your battery. Also, you can use it for a longer period of time as a result. In fact, you can use a quality LiFePO4 battery for many years longer than other battery types. It’s rated to last about 5,000 cycles. That’s roughly 10 years. So the average cost over time is much better. That’s how LiFePO4 batteries stack up vs lithium ion.
Here’s why LiFePO4 batteries are better than not just lithium ion, but other battery types in general:
Ασφαλής, Σταθερή Χημεία
Lithium battery safety is important. The newsworthy “exploding” lithium-ion laptop batteries have made that clear. One of the most important advantages LiFePO4 has over other battery types is safety.
Overall, LifePO4 batteries have the safest lithium chemistry. Because lithium iron phosphate has better thermal and structural stability. This is something lead acid and most other battery types don’t have at the level LiFePO4 does. LiFePO4 is incombustible and can withstand high temperatures without decomposing. It’s not prone to thermal runaway, and will keep cool at room temperature.
Εάν υποβάλετε μια μπαταρία LiFePO4 σε σκληρές θερμοκρασίες ή επικίνδυνα συμβάντα (όπως βραχυκύκλωμα ή σύγκρουση) δεν θα προκαλέσει πυρκαγιά ούτε θα εκραγεί. Για όσους χρησιμοποιούν μπαταρίες βαθύ κύκλου LiFePO4 καθημερινά σε RV, σκάφος μπάσου, σκούτερ ή πόρτα ανύψωσης, αυτό το γεγονός είναι παρήγορο.
Περιβαλλοντική Ασφάλεια
LiFePO4 batteries are already a boon to our planet because they’re rechargeable. But their eco-friendliness doesn’t stop there. Unlike lead acid and nickel oxide lithium batteries, they are non-toxic and won’t leak. You can recycle them as well. But you won’t need to do that often, since they last 5000 cycles. That means you can recharge them (at least) 5,000 times. In comparison, lead acid batteries last only 300-400 cycles.
Εξαιρετική Αποδοτικότητα και Απόδοση
Θέλετε μια ασφαλή, μη τοξική μπαταρία. Αλλά θέλετε επίσης μια μπαταρία που θα έχει καλή απόδοση. Αυτά τα στατιστικά αποδεικνύουν ότι το LiFePO4 προσφέρει όλα αυτά και πολλά άλλα:
Αποδοτικότητα φόρτισης: μια μπαταρία LiFePO4 θα φτάσει σε πλήρη φόρτιση σε 2 ώρες ή λιγότερο.
Ποσοστό αυτοεκφόρτισης όταν δεν χρησιμοποιείται: Μόνο 2% ανά μήνα. (Σε σύγκριση με 30% για τις μπαταρίες μολύβδου οξέος).
Ο χρόνος λειτουργίας είναι υψηλότερος από τις μπαταρίες μολύβδου οξέος/άλλες μπαταρίες λιθίου.
Σταθερή ισχύς: ίδια ποσότητα ρεύματος ακόμα και όταν η διάρκεια ζωής της μπαταρίας είναι κάτω του 50%.
Δεν χρειάζεται συντήρηση.
Μικρό και ελαφρύ
Πολλοί παράγοντες επηρεάζουν τη βελτίωση των μπαταριών LiFePO4. Μιλώντας για ζύγιση - είναι εντελώς ελαφριά. Στην πραγματικότητα, είναι σχεδόν 50% ελαφρύτερες από τις μπαταρίες οξειδίου του μαγγανίου λιθίου. Ζυγίζουν έως και 70% ελαφρύτερα από τις μπαταρίες μολύβδου οξέος.
When you use your LiFePO4 battery in a vehicle, this translates to less gas usage, and more maneuverability. They are also compact, freeing up space on your scooter, boat, RV, or industrial application.
Μπαταρίες LiFePO4 έναντι μπαταριών μη λιθίου
Όταν πρόκειται για LiFePO4 έναντι ιόντων λιθίου, το LiFePO4 είναι ο ξεκάθαρος νικητής. Πώς όμως συγκρίνονται οι μπαταρίες LiFePO4 με άλλες επαναφορτιζόμενες μπαταρίες στην αγορά σήμερα;
Μπαταρίες μολύβδου οξέος
Οι μπαταρίες μολύβδου οξέος μπορεί να είναι μια συμφωνία στην αρχή, αλλά θα σας κοστίσουν περισσότερο μακροπρόθεσμα. Αυτό συμβαίνει γιατί χρειάζονται συνεχή συντήρηση και πρέπει να τα αντικαθιστάτε πιο συχνά. Μια μπαταρία LiFePO4 θα διαρκέσει 2-4 φορές περισσότερο, με μηδενική συντήρηση.
Μπαταρίες Gel
Όπως οι μπαταρίες LiFePO4, οι μπαταρίες gel δεν χρειάζονται συχνή επαναφόρτιση. Επίσης, δεν θα χάσουν τη φόρτισή τους κατά την αποθήκευση. Πού διαφέρουν το gel και το LiFePO4; Ένας μεγάλος παράγοντας είναι η διαδικασία φόρτισης. Οι μπαταρίες gel φορτίζονται με ρυθμό σαλιγκαριού. Επίσης, πρέπει να τα αποσυνδέσετε όταν είναι 100% φορτισμένα για να μην τα καταστρέψετε.
Μπαταρίες AGM
AGM batteries will do plenty of damage to your wallet, and are at high risk for becoming damaged themselves if you drain them past 50% capacity. Maintaining them can be difficult as well. LiFePO4 Ionic lithium batteries can be discharged completely with no risk of damage.
Μια μπαταρία LiFePO4 για κάθε εφαρμογή
Η τεχνολογία LiFePO4 έχει αποδειχθεί ευεργετική για μια μεγάλη ποικιλία εφαρμογών. Εδώ είναι μερικά από αυτά:
Fishing boats and kayaks: Less charging time and longer runtime means more time out on the water. Less weight allows for easy maneuvering and a speed boost during that high-stakes fishing competition.
Mopeds and mobility scooters: No dead weight to slow you down. Charge to less than full capacity for impromptu trips without damaging your battery.
Solar setups: Haul lightweight LiFePO4 batteries wherever life takes you (even if it’s up a mountain and far from the grid) and harness the power of the sun.
Commercial use: These batteries are the safest, toughest lithium batteries out there. So they’re great for industrial applications like floor machines, liftgates, and more.
Πολύ περισσότερο: Επιπλέον, οι μπαταρίες φωσφορικού σιδήρου λιθίου τροφοδοτούν πολλά άλλα πράγματα. Για παράδειγμα – φακοί, ηλεκτρονικά τσιγάρα, ραδιοεξοπλισμός, φωτισμός έκτακτης ανάγκης και πολλά άλλα.
LiFePO4 Quick Answers
Is LiFePO4 the same as lithium ion?
Not at all! The LiFePO4 battery has a cycle life of over 4x that of lithium ion polymer batteries.
Can LiFePO4 catch fire?
LiFePO4 batteries are the safest of the lithium batteries, because they will not catch fire, and won’t even overheat. Even if you puncture the battery it will not catch fire. This is a massive upgrade over other lithium batteries, which can overheat and catch fire.
Is LiFePO4 better than lithium ion?
The LiFePO4 battery has the edge over lithium ion, both in terms of cycle life (it lasts 4-5x longer), and safety. This is a key advantage because lithium ion batteries can overheat and even catch fire, while LiFePO4 does not.
Why is LiFePO4 so expensive?
LiFePO4 batteries are usually more expensive on the front end, but cheaper long term because they last so long. They cost more up front because the materials used to build them are more expensive. But people still choose them over other batteries. Why? Because LiFePO4 has many advantages over other batteries. For example, they’re much lighter than lead acid and many other battery types. They’re also much safer, they last longer, and require no maintenence.
Is LiFePO4 a lipo?
No. Lifepo4 has a number of distinct advantages over Lipo, and while both are lithium chemistries, they are not the same.
What can I use LiFePO4 Batteries for?
You can use LiFePO4 batteries for the same things you’d use lead acid, AGM or other traditional batteries for. For example, you can use them to power bass boats and other marine toys. Or RVs. Or solar setups, mobility scooters, and much more.
Is LiFePO4 more dangerous than AGM or lead acid?
Nope. It’s actually quite a bit safer. And for a number of reasons, including the fact that LiFePO4 batteries don’t leak toxic fumes. And they don’t spill sulfuric acid like many other batteries (like lead acid.) And like we mentioned earlier, they don’t overheat or catch fire.
Can I leave my LiFePO4 battery on the charger?
If your LiFePO4 batteries have a battery management system, it will prevent your battery from overcharging. Our Ionic batteries all have built-in battery management systems.
What is the life expectancy of LiFePO4 batteries?
Life expectancy is one of the biggest perks, if not the biggest perk of LiFePO4. Our lithium batteries are rated to last around 5,000 cycles. That is, 10 years or so (and often more), depending on usage of course. Even after those 5,000 cycles, our LiFePO4 batteries can still function at 70% capacity. And better still, you can discharge past 80% without a single issue. (Lead acid batteries tend to gas out when discharged past 50%.)
